Some other info just in case you're not aware or if you consider buying a different year set of forks.
98-02 Milles are all Axial mount.
All 2003 first generation Mille's are Radial mount EXCEPT the Haga edition. The Haga editions are really 02 RSV R's and are Axial mount.
All the second generation RSV-R Factories are radial mount.
Let me know if you need some info or measurements, i have an 03 Mille R and can help you out if you need.
and the RC51 bottom is 54mm not 52mm like RC51racer stated.
